Flashcards in Lecture 7.3 Deck (34):
The Lumbosacral joint is a _______ ________ joint
The Lumbosacral joint is a secondary cartilaginous joint
Hyaline cartilage lining the articular surfaces
The joint between the sacrum and illium is the....
It is weight bearing?
The pubic synphyseal is a _____ cartilaginous joint
The intervertebral disc between L5/S1 is ))) shaped
Lumbar _____ turns to sacral ______
Lumbar lordosis turnsto sacral kyphosis
Along with the anterior longitudinal ligament, which other ligaments strengthen the lumbosacral joint?
lumbosacral and illiolumbar ligaments
The lumbosacral joint is between the bodies of ___/___
and the articular facet
The illiolumbar joint is between the
crest of the illium and the transverse process of L5
sacroilliac joint is important for _____ of human body
b/w sacrum and illiac surface of pelvis
The sacral _______ makes up the illiosacral joint
The sacral tuberosity makes up the illiosacral joint
(locks up the the illac tuberosity)
The interosseus ligaments lies at the sacral tuberosity - this is an example of a ...
The interosseus ligaments lies at the sacral ______ - this is an example of a syndesmosis
The syndesmosis in the sacroiliac joint helps to...
pass weight to the pelvic bone from the sacrum
There are also anterior and posterior ______ ligaments that assist alongside the interosseous membrane
The ______ligaments converts the lesser sciatic notch into the lesser sciatic foramen
The scarospinous ligaments converts the lesser sciatic notch into the lesser sciatic foramen
The accessory ligaments of the sacroilliac joint are..
what are they important for
Sacrospinous and sacrotuberous
Jumping, carrying bags
Any way in which weight is being transferred up from the pelvis - help keep the joint in place
The mainline of gravity goes _____ to thWhen there is a tendency for the sacrum to move forward - the _____ ligaments tighten and pull ______- open up the pelvic inlete lumbosacral joint
The mainline of gravity goes anterior to the lumbosacral joint
When there is a tendency for the sacrum to move forward - the _____ ligaments tighten and pull ______- open up the pelvic inlet
When there is a tendency for the sacrum to move forward - the interosseous ligaments tighten and pull together - open up the pelvic inlet
The sacrum is analagous to the reverse keystone effect - whereby...
the arch helps the hold the sacrum (Keystone) up
The roles are reversed
the tendancy to tilt forward to wight transfer is stopped by the strong ligaments (interosseous) that lock in place and pull the "arch" back into position
The illiosacral ligaments relax during ______
the pubic symphysis works a a "tie-beam" prevents separation _____ and resisting compression forces via ____
the pubic symphysis works a a "tie-beam" prevents separation laterally and resisting compression forces via femora
What are the ligaments of the pubic symphysis
Superior - along the pubic crest
arcuate - underneath
The pubic symphysis is reinforced by criss-crossing fibres from _____ muscles
The pubic symphysis is reinforced by criss-crossing fibres from abdominal muscles
Anterior and posterior _______ ligaments hold the scarococcygeal joint together
The pretzel concept explains how pelvic fractures on one side will cause..
a fracture on the other side as well
what is spondylolysis
a defect in the pars interarticularis of the vertebral arch. The great majority of cases occur in the lowest of the lumbar vertebrae (L5), but spondylolysis may also occur in the other lumbar vertebrae, as well as in the thoracic vertebrae.
Spondylolisthesis is the forward displacement of a vertebra, especially the fifth lumbar vertebra, most commonly occurring after a break or fracture
clearly worse than spondylolysis- sciatic nerve in danger
what are the margins of the hip joint capsule?
The illiofemoral ligament is __ shaped\
where does it insert?
inserts on the intertrochanteric line of the femur
The ______ ligament also inserts on the intertrochanteric line of the femur
_______ligaments fibres spiral from posterior side and meet up with the fibres at the _______ line
Ishiofemoral ligaments fibres spiral from posterior side and meet up with the fibres at the intertrochanteric line
All 3 ligaments in the hip joint tighten in hip _____ rotation and ______
all 3 ligaments in the hip joint tighten in hip internal rotation and extenion
Hip joint stability is best when in ______ , slight ____ and _______rotation
Hip joint stability is best when in extension, slight abduction and internal rotation - ligaments are tightest
Hip dislocation is more common in the ____ direction
Sitting with legs crossed - force from the front
